BRIDGEPORT — Police are investigating an assault that sent a prominent councilwoman to the hospital.

Councilwoman Eneida Martinez suffered unspecified injuries Wednesday night requiring medical attention, said police spokesman Av Harris. Harris could not elaborate further but said the matter is under investigation.

But a source within the department said an arrest warrant for assault had been secured and an arrest was pending.

“I’m wishing her a speedy recovery and healing thoughts and prayers from her colleagues,” said Council President Aidee Nieves.

“She’s in our prayers,” said Councilman Ernie Newton, who, along with Martinez, represents the East End.

Martinez was first elected to the 139th Council District in 2013 and is an active, passionate and sometimes controversial legislator. She chairs the ordinance committee and serves on the economic development and public safety committees.

Most recently, Martinez has been helping spearhead the council’s probe into how the Water Pollution Control Authority pursues delinquent sewer bill fees and the private collection attorneys engaged for that work by the city.

“I hope she’s OK,” said Councilman Marcus Brown, a freshman member who is Martinez’s co-chairman on the ordinance committee. “Eneida is not the right person to mess with. She is a tough person — probably the toughest I know.”
